I agree, if a clock is bound to a sub-device beforehand it could 
probably be done with just a callback as well. Implementing default 
behaviour at the framework makes a lot of sense too, it could ease 
the conversion process significantly.

Indeed, I hope it won't take too much time before at least some of the
platforms get converted.
